And, the answer for the the question is :
Explanation:
Electric telegraphs were the first means of instantaneously communicating across great distances. Written communication could be transmitted across continents using electrical pulses. Lines are a system of conductive wires used in early telephones to transmit voice calls. A person’s voice might now be heard from hundreds of miles away.
The telephone is one of the most important inventions in human history, revolutionizing communication and bringing people closer together. The first modern telephones, which were invented by Alexander Graham Bell in the late 1800s, transmitted sound using electricity.
The basic principle of the telephone is simple. When a person speaks into a microphone, the sound waves produced by their voice cause a diaphragm to vibrate. This vibration creates an electrical signal that can be transmitted over a wire to a receiving device, which converts the electrical signal back into sound waves that can be heard by the listener.
In the early days of the telephone, this process was accomplished using a simple device known as a transmitter. The transmitter consisted of a diaphragm and a metal contact, which were separated by a small amount of carbon granules. When the diaphragm vibrated, it compressed the carbon granules, causing their resistance to electricity to change. This change in resistance created an electrical signal that could be transmitted over a wire to a receiving device.
The receiving device, known as a receiver, consisted of a magnet and a coil of wire. When an electrical signal was transmitted over the wire, it caused the magnet to vibrate, which in turn caused the diaphragm to vibrate and produce sound waves that could be heard by the listener.
Over the years, the technology used in telephones has evolved significantly, with the introduction of new materials, components, and manufacturing techniques. However, the basic principle of transmitting sound using electricity remains the same.
